Definitions

  • the present invention relates to an article holder for use in an embossing machine and, more particularly, to a holder for embossing wooden articles of irregular cross-section.
  • U.S. Pat. No. 773,854 discloses a device for embossing a spindle, column or baluster which has been turned or otherwise formed in the general shape desired.
  • the article to be embossed is passed between a pair of rotating wheels or rollers each provided with one or more die blocks on the surfaces thereof.
  • the die blocks are curved so that, when it contact with the article, all of the faces thereof to be ornamented are simultaneously engaged by the dies.
  • four wheels are utilized, with each wheel embossing a corresponding quadrant on the article.
  • U.S. Pat. No. 792,781 discloses an embossing die which automatically transversely compresses the article being embossed to prevent the article from splitting longitudinally during the embossing operation.
  • a separate abutment flanks the pattern surface of the die along the entire length of each side.
  • the insides of the abutments are preferably tapered slightly inward.
  • the material to be embossed is a width slightly greater than the distance between the abutments at a point just beyond the highest cutting points of the embossing surface so that, when the material is forced into engagement with pattern surface of the die, the material will be clamped between the abutments and thus held against splitting.
  • U.S. Pat. No. 3,229,401 discloses a device for embossing a gun stock in which a hollow stock is held on a gun stock mount carried on a frame. In this patent, from one to three dies are carried by the frame and are moved into engagement with the surface of the stock to emboss it.
  • U.S. Pat. No. 3,621,897 discloses a process for producing a compressed wood component which has ornamentation embossed therein.
  • the component is placed on top of an upwardly facing die and downwardly directed pressure is applied to the component to force it into the die.
  • the die includes an upstanding edge which completely surrounds the pattern area of the die.
  • U.S. Pat. No. 3,764,767 discloses a heated wheel which rotates against continuous stock fed through a channel on the bed of the embossing machine.
  • the channel prevents movement of the stock with respect to the wheel in a direction transverse to the feed direction.
  • the article being embossed is of uniform cross-section.
  • an article of irregular cross-section such as a leg for a piece of furniture
  • the present invention concerns a holder for embossing articles of irregular cross-section such as chair legs and the like.
  • a lower base which can be a heated machine platen, supports a lower base plate and a lower embossing die.
  • Four upstanding guide posts are spaced from the die at the corners of the base plate and extend through corresponding apertures in a lower support plate.
  • the lower support plate is spaced from the lower base plate by helical springs coaxial with the support posts and has a central opening formed therein for receiving the lower die.
  • a pair of support blocks are mounted on an upper surface of the support plate and are spaced to engage opposite ends of an upwardly facing work piece such as a chair leg.
  • An upper heated machine platen is spaced above the lower heated machine platen and has a downwardly facing surface on which is mounted an upper base plate.
  • a pair of downwardly facing support blocks, for engaging opposite ends of the chair leg, and an upper embossing die extend downwardly from the upper base plate.
  • the upper die embossing surface contacts the chair leg and the downwardly facing support blocks are positioned adjacent the ends of the leg to limit any relative movement either by rotation or cantilevering.
  • the lower support plate is moved downwardly against the biasing springs until the lower die embossing surface engages the leg.
  • equal pressure is being applied to the chair leg by the upper and lower embossing dies and the support blocks continue to limit any movement of the chair leg relative to the embossing dies.
  • FIG. 1 is a front elevational view of the embossing tool according to the present invention and illustrating the upper and lower die sections in an open position.
  • FIG. 2 is a sectional view of the embossing tool taken along the line 2--2 of FIG. 1;
  • FIG. 3 is an end view of the embossing tool according to the present invention illustrating the upper and lower die section in a closed position.
  • FIGS. 1 and 2 there is shown a portion of an embossing machine having a lower platen 10 fixed to a machine bed (not shown) and a spaced apart, upper platen 11 moveable downwardly toward the upwardly facing surface of the lower platen 10 by a pressure applying mechanism (not shown).
  • a pressure applying mechanism not shown
  • the upwardly facing surface 12 of the lower platen 10 has mounted thereon a base plate 13 having a central aperture 14 formed therein.
  • a lower embossing die 15 is mounted on the surface 12 of the platen 10 and extends upwardly through the aperture 14.
  • the lower die 15 has an upwardly facing embossing surface or face 16 contoured to represent the negative of the pattern to be embossed on a chair leg.
  • Each of the guide posts 17 has associated therewith an encircling helical spring 18.
  • the guide posts 17 extend through the centers of the respective helical springs 18 which in turn rest on an upper surface 19 of the base plate 13.
  • a support plate 20 has a plurality of apertures 21 formed therein through which the guide posts 17 extend such that the support plate 20 rests on the upper ends of the helical springs 18.
  • the support plate 20 also has a large central opening or aperture 22 formed therein through which the lower die 15 extends. While the drawings illustrate the opening 22 as centrally located such that the support plate 20 completely surrounds the lower die 15, it will be appreciated that, in some instances, it may be desirable to form the opening such that the die 15 is only partially surrounded.
  • a pair of support blocks 24 and 25 are mounted on an upper surface 23 of the support plate 20.
  • the support blocks 24 and 25 each have an upwardly facing, notch formed therein for supporting the chair leg at the respective ends thereof.
  • the support block 24 has a V-shaped notch 26 formed therein which conforms with a portion of the outer surface of the larger end of a chair leg 27.
  • the support block 25 (FIG. 2) has a similar notch formed therein for supporting the smaller cross-sectional area end of the chair leg 27.
  • the support blocks 24 and 25 and their corresponding notches are dimensioned such that the chair leg 27 resists rotation and is held in position in the tool with its longitudinal axis in a generally horizontal plane.
  • the base plate 29 has a central aperture 30 formed therein.
  • An upper die 31 is mounted on the lower surface 28 and extends downwardly through the aperture 30.
  • the die 31 is provided with a downwardly facing embossing surface 32.
  • the base plate 29 has a downwardly facing lower surface 33 upon which are mounted four downwardly extending guide blocks 34.
  • An aperture 35 is formed in each of the guide blocks 34 and extends from a downwardly facing surface thereof through the guide block 34 and through the base plate 29 to the lower surface 28 of the upper platen 11.
  • the apertures 35 are dimensioned to accept the upper ends of the guide posts 17 as the upper platen 11 is lowered to prevent relative horizontal movement between the upper die 31 and the lower die 15.
  • the support block 36 is aligned with the support block 24 and has a downwardly opening V-shaped notch 38 formed therein.
  • the notch 38 is contoured to conform to the upper outer surface of the chair leg 27.
  • the support block 37 is aligned with the support block 25 and has a similar notch dimensioned to limit movement of the smaller end of the chair leg 27.
  • the support blocks 24 and 25 cooperate with the support blocks 36 and 37 respectively to limit any rotation of the chair leg 27 about its longitudinal axis 39 or any cantilevering of the chair leg 27 when the upper die 31 and the lower die 15 engage the chair leg 27.
  • the notches in the support blocks can be of any suitable shape as dictated by the object to be embossed.
  • the chair leg 27 is positioned in the notches of the support blocks 24 and 25 above the lower die 15.
  • the upper platen 11 is then lowered so that the embossing surface 32 of the upper die 31 engages the upper surface of the chair leg 27.
  • the chair leg 27 and the support plate 20 will be forced downwardly against the biasing springs 18 and the lower surface of the chair leg 27 will engage the embossing face 16 of the lower die 15.
  • the lower die 15 and the upper die 31 will exert equal pressure upon the chair leg 27 to emboss the chair leg uniformly to the desired depths.
  • the upper platen will continue to move downwardly until the desired embossing depth is achieved.
  • the support blocks 24, 25, 36 and 37 limit movement of the chair leg 27 with respect to the embossing dies 15 and 31.
  • the support blocks 36 and 37 do not contact the leg 27 unless the leg shifts upwardly with respect to the support blocks 24 and 25.
  • a stop block 40 attached to the upper surface 23 of the support plate 20 and positioned adjacent the surface of the support block 24 opposite the aperture 22, provides a longitudinal locating point for the larger end of the chair leg 27 and prevents any longitudinal shifting at the dies are closed.
